Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

One time I mentioned to my boss how I think humanity is doomed to destroy life on Earth because we never learn from our mistakes until it's too late.

My boss said that she is optimistic that we'll get climate change under control because of her young daughter's generation. I immediately backpedaled and agreed that we'll probably figure it out and technology will save us, but I was just lying to both of us feel better.

Of course we need to keep trying to solve these climate issues, but a lot of people are in denial about how bad things already are and underestimate the kind of societal shifts that need to happen right now because of the cognitive dissidence many of us hold, even scientists.

I would have responded with how many gen y/z are in congress right now if someone was that optimistic.

Based on current trends, I'd say 40 more years until gen-z is old enough to get seats in Congress! 👴👵
